Will it be possible to upload photos of more than 2Mb during the resizing process, otherwise we get a nice error from the libray used by the forum. 250Kb is ok for viewing but nowdays most of us using smartphone or camera have 2-10 Mb jpg photo as source uploaded to the forum. We have to resize them before uploading and then the forum itself reduce them to 200Kb.
It's just an option in the php ini to change and it won't use much space on the hosting space disk. Just used as temporary file.
thanks
